| Wave Solder CAS761 Sheet |
Description
Changda wave solder pallet material is a fiber-reinforced plastic for mechanical and electrical applications. With a good performance against electric arc and tracking, it is an ideal material for solder paste printing, SMT process, reflow soldering, and wave soldering.
Characteristics
-Good Anti-static property
-High strength and good machinability
-High-temperature resistance
-Tight machining tolerance
-Chemical resistant
-Long life cycle
Durostone's function in PCB assembly
1. Avoid pollution due to human contact
2. Reduce disposal rate
3. Prevent PCB from bending
4. Standardize the width of the production line
5. Improve production capacity by using multi-functional fixtures
6. Cover the SMT parts at the bottom, make the partial welding available
Wave solder material 's function in wave soldering
It can keep its physical properties at increasing high temperatures. So it can reach high precision without any deformation. There are no layering, bubbles, deformation when working at 380 ° C for a short time.
We can also design pallets as per client's requirement. Below information is necessary for the pallet design.
